Overview

Frequency is the reciprocal of the period. For a pendulum, it represents the number of complete oscillations (back and forth) per unit of time.

Fun Facts

"A pendulum with 1 meter length has a frequency of about 0.5 Hz on Earth."
"The frequency of a pendulum is used in grandfather clocks to maintain steady time."
"Frequency is independent of the mass of the bob and the amplitude (for small angles)."

Formula: f = (1 / 2π) · √(g / L)
